WILLIAM-LOTTQARZLhl'GER, or'iq sHvI LE, TENNESSEil.-. I

a citizen of the United States, .and a resident Y of Nashville, in the county of Davidson and State of Tennessee, have invented a new and useful Improvement in Sand-Separators, of

which the following is, a specification.

My invention relates to improvements in devices for separatingmaterials, more particularly for separatlng sand or grit from V graphite inthe process of refining the latter,

and it consists in the combinations, constructions and arrangements herein described and claimed.

An object of myinventionfis to provide a simple device by means of which the graphite may be separated from the sand continuously, that is to say,.without necessitating the stopping of the apparatus, to take away'portions of the separated graphite.

' A further object of my invention is to provide a separatorwhich is of simple construction, has few parts, is not easily liable to get out of order, and which may be readily assembled. i

I Other objects and advantages will appearin the following specification, and the novel features of theinvention will be particularly pointed out in the appended claim.

My invention is illustrated in the accompart of this apcasing 1, this casing being preferably of a cylindrical shape and having a bottom 2 which is provided with a central flanged opening 3. a V:

Extending upwardlv through this opening3 is a pipe 4. The upper end of the casing has a conical shapeas shown at 5,

and terminates in a central 'fianged openmg 6. L V I A pipe 7 extends downwardly through the opening 6. This pipe is provided with a ser es of'p rforations8 but is closed at its bottom with a con calr e nber 9., A the en of t e pipe 7 is a d flector or b ffle 10.

This baffle is of conical shape and is pro is disposed at the bottom "ftot me bv opening the door 12.

vided with a sleeve-11 which is threaded to hold their respective pipes 4 and 7, securely.

It will be noted that the pipe l passes through the bottom 8 and eXtendspa-rtly engaget hethreaded end ofthe pip'e'lf The I openings 3'*and-6 are also threaded so to into the interior of the casing 1. Aidoor 12 one side thereof. 1

' From the foregoing description of the various parts of the device the operation thereof maybe readily understood. The

mixed sand and graphite is forced through i V the pipe 4 by any suitable means. In a copending application I have set forth the means y which this is done, this means be ing a fan or blower. The graphite and sand passes up through the pipe 4, being pro Jected against the'bafiie or deflector 10'; The

sand having a slightly greater specific gravity than the graphite, tends to bound of the casing on backwardly toward the bottom of the'cylin der or casing; the'elasticity of the sand be f ing greater also, tends to cause this action.

The graphite being of-a flaky nature, is.

caught by the air current and passes around the edge of the deflector or baffle 10 and then is drawn through the perforations 8,

into the pipe 7 and then out through the aids in separating a considerable quantity of the sand from thegraphitewhich has been carried arcundthe edge of the deflector by the air currents. Apparently, the graphite being in the form offlakes is more easily carried along by the currents or turned j from its path into the pat of the currents. These openings 8, as it will be seen, are not so close as to form agrating. but are preferab y arranged in rows, leaving a considerable space between the rows so thatthe air Order to pass through these perforatons The sand which fallsdownwardlv collectscurrents actually changetheir cour'ses in' below thelend of the p pe- 4 on the bottom of] the casing 1, and may be'remo el from time a V The'device works continuous y. and be BflSjlV taken apart for inspection or remay pair, although the few parts and therelative simpl city of the device obviates the necessity of mnch attention on the part of the. u er of the device. r a

I claim:

I 85' 17: pipe 7. I find that the perforated pipe 7 Y p VA sand separator comp ising a cvl n'dr cal V V casing; an inlet pipe, for conveying air,-

flakegraphite, and sand, extending into the bottom of the casing, the end of the inlet pipe being above the bottom; said casing having a conical top provided with an opening; a discharge pipe extencling through said ,openlng 1n the top'of the caslng; said 7 discharge pipe having aportion extending downwardly into the casing, said downwardly extending portion having perforations in its sides, for the passage of a1r and V graphite; the bottom end of the pipe being closed with a hollow conical member; and

low bafiie eing spaced from the end ofthe' inlet pipe, substantially as described. WILLIAM OTTO ARZINGER.
